about the other side or were you surprised by some things? >> what was surprising is that you don't interact much with the other side. >> at the end of the day just like well behaved fans in a sports stadium. you can respect each other, you're both passionate about football and you find those common things even though you might be rooting for different teams. >> i think members of both groups obviously, like she said, have the same, a lot of the same opinions actually on things. sometimes it's more just a matter of how we get to the end. >> reporter: two weeks from tonight, 50% of this little group will triumph, 50% will be bitterly disapointed. the challenge for the winner, whoever he may be, will be to unite them, if he can. i'm david wright for "nightline" in denver. >> david wright, building bridges. thanks to him. just to him, he's been rocking out for decades and now rod stewart is coming clean about his modeling days, those
